摘要： A nozzle assembly for an inkjet printhead. The nozzle assembly includes a nozzle chamber with a roof having a nozzle opening defined therein. The roof includes a moving portion moveable relative to a stationary portion, such that movement of the moving portion relative to the stationary portion causes ejection of ink through the nozzle opening. The nozzle assembly also includes an actuator for moving the moving portion and a seal member. The seal member is configured as a bridge spanning between the moving portion and the stationary portion.

摘要： A printhead (100) includes a common ink chamber (104) or reservoir bounded on one side by a membrane (106) having nozzle apertures (120,122,124). The membrane (106) forms a print face of the printhead (100). Piezoelectric elements (108,110,112) are located on the membrane (106) near the nozzles (120,122,124). The piezoelectric flex segments of the membrane (106) surrounding the nozzles (120,122,124) to eject ink droplets from the nozzle apertures (120,122,124). Ribs (330,332) are also provided on the membrane (106) and define boundaries of the membrane segments corresponding to the nozzles (120,122,124). The ribs (330,332) can isolate each nozzle from the other nozzles, in two ways. First, the ribs (330,332) act as stiffeners so that when the piezoelectric elements (108,110,112) attached to one membrane segment flex that membrane segment, the other membrane segments are not significantly flexed. Second, when the ribs (330,332) are provided on an interior surface of the membrane (106), they deflect the pressure pulse in the ink fluid from a flexing membrane segment, upwards, away from adjacent membrane segments/nozzles.

摘要： Contemplated printheads include a piezoelectric material in which a channel is formed across the piezoelectric material to thereby create at least part of the nozzle through which ink is expelled from the inside of the printhead to the outside. Contemplated nozzles may be configured as cylindrical elements or ring-shape elements. Consequently, application of a voltage across the piezoelectric channel may result in constriction of the cylindrical element or convex/concave deformation of the ring-shape element. Most preferably, the piezoelectric material, conductive traces, and supporting structures are applied from a liquid phase to a carrier, and shaped using photolithographic methods.

摘要： An inkjet printhead chip includes a wafer substrate (116). Drive circuitry is positioned on the wafer substrate. A plurality of nozzle arrangements is positioned on the wafer substrate. Each nozzle arrangement includes nozzle chamber walls (132) and a roof wall positioned on the wafer substrate to define a nozzle chamber (134) and an ink ejection port (124) in the roof wall. A micro-electromechanical actuator (128) is connected to the drive circuitry. The actuator includes a movable member (130) that is displaceable on receipt of a signal from the drive circuitry. The movable member defines a displacement surface that acts on ink in the nozzle chamber to eject the ink from the ink ejection port. An area of the displacement surface is between half and twice a cross sectional area of the ink ejection port.
